Native name " Tawarc " (P. 0. S.). 



This subspecies of the Tayra is characterized by its general 

 brown colour, all the other forms — including the one described 

 by Tschudi from Peru, on which Dr. Nehring's "peruana" 

 is presumably based — being either black, or, if at all brownish, 

 at least with a wholly black tail.

 rufous on the sides. Face more greyish. Under surface 

 white throughout, or the extreme bases of the hairs slaty ; 

 line of demarcation on sides well defined. Ears of medium

 like back, fingers white; outer side of hind limbs fulvous, 

 darkening to brown on the distal part of the metatarsus, 

 toes white. Tail well-haired, pencilled, uniformly blackish 

 brown.
